Hollywood star Brad Pitt and Angelina Jolie are planning to adopt a little girl from Africa - because the actress wants to "save" another child from the poverty-stricken continent. The couple already has a brood of four - adopted Maddox, six, from Cambodia; four-year-old Pax from Vietnam; two-year-old Zahara from Ethiopia, and their only biological child, Shiloh, one. But the Mr. + Mrs Smith co-stars have already expressed their desire to expand their young family, and Jolie's brother James Haven reveals they are set to return to Africa to look for a little sister for their four kids. He says, "They are creating one big family and will keep adopting as long as they are able to. "Angie and Brad talk about how much they've been taught by their kids. In many respects, Angie saved Zahara's life and there are so many more children whose live she could save and she talks about that constantly." According to British tabloid the Daily Mirror, Pitt and Jolie will start looking at African orphanages over Easter (Mar08).
